Three Heron nests

We’ve watched nesting Great Blue Herons since we moved to Independence (for example 2014, 2015). The one nest in 2014 became two last year and now we have three – I imagine that the new nests are previous years young, returning to where they grew up.
The original nest and last years addition are both in the tree in the center of Lake Koval behind our home; the higher one is easy to see, while the lower is buried in other growth – but if you compare these two closer views, you’ll spot where the lower Herons are:


The third nest is in a tree over to the left and outside the above views (it’s actually the tree that was hit by lightning last year); it’s closer to easier to get pictures; the nest is halfway down the left of the right tree:

I wonder how many birds there will be next year?!
